Abstract

The high performances of Dynamically Innovative BSCCO (DI‐BSCCO) wire have been reviewed. Critical current
has reached 210 A (77 K and self‐field), which is equivalent 500 A per 10 mm width, by total optimization of whole manufacturing process including Controlled Over Pressure (CT‐OP) sintering. The further higher
value will be available on preferable oxide filaments with the improved c‐axis orientation of Bi2223 grains, the minimized non‐superconducting phases, and so on. The
of long length wires has been reached 203 A of 42 m 180 A of 1,400 m.
in the magnetic field at low temperature has showed great improvements in comparison with the past 150 A class wire. The mechanical performances has been improved due to the densification of the Bi2223 filaments up to 100% by CT‐OP process, moreover have been dynamically improved by reinforcement with stainless steel tapes or brass tapes. These results can enable DI‐BSCCO wire to be applied for the cryogenic applications such as motors, magnets, cables and so on.
